Abstract (en)
[origin: DE19920804A1] The first material (40) with an embossed pattern on it is laminated to a second material (43) by a process using a point lamination pattern (56) provided on a heated calender roll (50). One or more geometric characteristics of the two patterns (41,56) such as bonding/contact area, pitch, or angle of axes, is selected and differentiated, prior to lamination, to control, during lamination, the amount of point mis-registration between the two patterns (41,56). The laminate (60) can have optimum all over lamination if the amount of point mis-registration is maximized. An adhesive may be provided between the first as second materials (40,43) to enable lamination of dissimilar composition materials. The weight of the first and second materials is respectively above or greater than, and less than 50 gram per square meter. The chemical composition of the first material is such as to make it unsuitable for bonding to the second material by heat and pressure alone. When the thermoplastic adhesive layer and the polymer layer are passed through the thermo-bonding calender, they are caused to melt together to form an integrated bond.
